EOBD* management:
The OBD (On Board Diagnostic) system enables the detection of any faults relating to the vehicle emission control
system (OBD EURO IV emission control standards exceeded).
This system should be active for the entire life of the vehicle.
1. Conditions causing an OBD fault
An OBD fault will be detected after 3 driving cycles and the following parameters will be registered in the computer:
–engine load,
–vehicle speed
–air temperature
–coolant temperature,
–turbocharging pressure,
–rail pressure,
–air flow,
–distance travelled in miles by the vehicle since activation of the OBD warning light.
It allows the driver to know whether the vehicle has a fault directly linked to the emission control system.
2. System faults indicated by the OBD
Only a few faults are indicated by the OBD system:
–DF001 Coolant temperature sensor circuit.
–DF003 Atmospheric pressure sensor circuit.
–DF011 Sensor feed voltage no. 1.
–DF012 Sensor feed voltage no. 2.
–DF013 Sensor feed voltage no. 3.
–DF038 Computer in 6.DEF EEPROM fault.
–DF040 Cylinder 1 injector circuit in CO Open circuit.
–DF041 Cylinder 2 injector circuit in CO Open circuit.
–DF042 Cylinder 3 injector circuit in CO Open circuit.
–DF043 Cylinder 4 injector circuit in CO Open circuit.
–DF054 Turbocharging solenoid valve control circuit in CC.0 Short circuit to earth.
–DF056 Air flow sensor circuit.
–DF209 EGR valve position sensor circuit.
–DF621 EGR valve jammed open.
Some repair operations require programming to ensure that certain engine components function correctly.
Follow the programming procedures (see Replacement of components), if replacing the exhaust gas
recirculation valve or an injector.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after repeated engine starts or with the engine running.
Special notes:
Use bornier Ele. 1681 or Ele. 1590 for all operations on the computer connectors.
If the fault is present:
–the engine will stop immediately,
–it is impossible to restart,
–the level 2 warning light is lit.
Priorities when dealing with a number of faults:
Deal with fault DF013 Sensor supply voltage no. 3 first, if it is present or stored.
CC.0
NOTESNone
Check the rail pressure sensor connectors.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation to earth of the following connections:
Injection computer brown 48-track connector B
track G3Track 2 rail pressure sensor
Brown 48-track connector B injection computer
track A4Track 3 rail pressure sensor
Repair if necessary.
If the fault is still present, replace the rail pressure sensor and tighten to 35 ± 5 Nm.
Follow the recommended safety advice (see cleanliness advice).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present following a road test or after attempting to start the engine
several times.
Special notes:
If the fault is present:
–the EGR function is inhibited,
–the engine stops,
–the level 2 warning light is lit,
–the OBD warning light will come on after three consecutive driving cycles (starting
+ 5 seconds + switching off the ignition and waiting 1 minute).
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
The sensors connected to supply no. 3 are:
–Rail pressure sensor.
–Air flow sensor..
To locate a faulty sensor and/or connection, disconnect one of these sensors then check whether the fault
becomes stored.
If the fault is still present, repeat the operation with the other sensors.
(Wait a few seconds after each disconnection so that the computer can carry out the check).
If the fault is stored after a disconnection, replace the faulty sensor or repair its connection.
Clear the faults created by the multiple disconnections.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Repair if necessary.
2. Check the insulation from + 12 V of the following connections:
Injection computer brown connector B track G3 Track 2 of the rail pressure sensor
Injection computer brown connector B track A4 Track 3 of the rail pressure sensor
Injection computer brown connector B, track C4 Track 1 of the rail pressure sensor
Injection computer brown connector B track G1 Track 5 of the air flowmeter
Injection computer brown connector B track B4 Track 3 of the air flowmeter
Injection computer brown connector B track E2 Track 2 of the air flow sensor
Injection computer brown connector B track L4 Track 6 of the air flowmeter
Repair if necessary.
3. Check the insulation between the following connections after disconnecting the sensors and the
injection computer:
Tracks 1 and 3 of the rail pressure sensor and tracks 2 and 3 of the air flow sensor connector.
If these checks do not produce the correct results, replace the faulty sensor(s).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
